Some lubricants would have the effect of replacing static friction with dynamic, if only because their bulk kept the solids offset from the static case. The general answer is no, however; the lubricant will present a new set of possible surface geometries in which the wetting energy is reduced, reactions to force changed, and of course the sliding friction case reactions reduced or changed as well.
Lubricants are characterized by their useful range for work; for example high-poly grease (2 million -mer where glycerin soap might be 30-250 -mer (i.e. that many carbons (on the case) in a chain)) is great for bicycle bearings and general machine use up to 5 meters per second; when trains need to go faster than that, you get to change wheel designs to run on oil (and different bearings, shifting the grease to duty on the suspension guide pins) so the lubricant isn't destroyed in seconds, in a manner very like a wool sweater on a drag-race wheel.1 Oil and powder lubricants degrade quickly at the common low-speed or high-load cases, though additives can help.

The basic idea of friction is to fitting the ups and downs of one surface into the ups and downs of other surface. Mostly, we cannot see ups and downs of surfaces with our naked eye as it is in molecular level. This lubricant's molecules goes and fits in to the ups and downs of our required surface and makes surface smoother so that these ups and downs of other surface cannot fit into the required surface. Thus lubricant reduces the friction.

Lubricants reduce friction by replacing sliding friction with fluid friction.
the correction option is true :)
True. Lubricants reduce friction by forming a thin layer between moving surfaces, which helps to replace sliding friction with fluid friction. This allows for smoother movement and decreased wear on the surfaces in contact.
Viscous lubricants, such as oils and greases, reduce friction by creating a fluid layer between moving surfaces. This fluid layer separates the surfaces, allowing them to slide past each other with less resistance. The viscosity of the lubricant determines the effectiveness of this fluid friction.
Sliding friction is determined by the nature of the surfaces in contact, their roughness, the force pressing the surfaces together, and the presence of any lubricants. The rougher the surfaces and the greater the force pressing them together, the higher the sliding friction. Lubricants can reduce sliding friction by providing a smoother surface for the two objects to slide against each other.
You can reduce sliding friction between two surfaces by using lubricants such as oil or grease to create a thin layer between the surfaces. Additionally, using materials with lower coefficients of friction, such as Teflon or nylon, can help reduce friction. Keeping the surfaces clean and smooth can also help minimize sliding friction.
Lubricating fluids have a sliding lattice structure which helps the atoms in the lattice to slide over each other and thus reduce the friction in the bodies in which they are applied. The relative sliding between the layers helps in lubrication.
You could add lubricants like oil or grease to reduce sliding friction on the moving parts of a machine. Additionally, using materials with lower coefficients of friction or adding bearings or rollers can help to minimize sliding friction. Regular maintenance and cleaning of the machine parts can also help prevent friction buildup.
Lubricants.
Use lubricants such as oil or grease to reduce friction between surfaces. Use smooth or polished surfaces to minimize roughness and friction. Ensure proper alignment and regular maintenance of moving parts to avoid unnecessary friction. Reduce the weight or force pressing the surfaces together to decrease friction.
Some ways to reduce the magnitude of friction are to use lubricants as they fill up in the irregularities and make the surface smoother, switch from sliding kinetic friction to rolling kinetic friction and by smooth surfaces that rub against each other.by polishing by streamlining in fluids . by ball bearing
